JRRT made an interesting writing somewhere that it was a possibiluty that the Balrog of Moria was indeed not a Balrog, but Saruman himself! However, it was discarder as Saruman (if he was a balrog) would have died and would then not have been seen later in LotR. However, it is an incredibly interesting concept that Tolkien considered this. Here is a few passages from the seventh volume of 'The History of Middle-earth: The Treason of Isengard'. The first is from page 236: On page 422 it says: The quotes are quite similar but I find it fascinating that Tolkien at one point considered the possibility that the Balrog of Moria could have Saruman. Anyone agree?
